The described modification relates to a specific alteration performed on the fuel tank of Ford trucks equipped with the 7.3-liter Power Stroke diesel engine. This adjustment typically involves shortening the fuel tank pickup tube. As an example, owners seeking improved fuel delivery at low fuel levels often consider it.
Implementing this change aims to mitigate fuel starvation issues, particularly when the fuel level is low and the vehicle is at an incline. Historically, it addresses a common complaint among owners who experienced engine stalling or reduced performance under such conditions. The perceived benefit is a more consistent and reliable fuel supply, potentially extending the usable range of each fuel tank.
